BACKGROUND OF THE INVENTION

This invention relates to construction of railing systems associated with stairs, balcony, landing or deck railings and particularly to the construction and attachment of balusters to such constructions.

In the construction of stairs, decks, balconies and the like, there is a need for installing railings and balusters between the railings and the base of the stair, balcony, landing or deck and there are frequent jurisdictional codes as to the size and spacing of balusters along such railings. The construction of railings and the installation of balusters with those railings at a job site can be time consuming in the spacing and attachment of the balusters between the railing and a base. The present invention is intended to provide a simplified apparatus for positioning and adjusting balusters along a railing installation.

The on site installation of balusters to a sloping stairway requires measurement and alignment of separate balusters to conform to the slope of the stairway. Because not all stairways are of the same slope, the installing of a baluster may require drilling mounting holes in a railing for connection of a baluster and aligning such holes with mounting holes along a base surface. The present invention provides a simplified means and method for installing balusters along a railing regardless of the slope of a stairway or the spacing between the railing and a base surface.

SUMMARY OF THE PRESENT INVENTION

In accord with the present invention baluster attachment to stair or balcony railing is accomplished using a ball joint attachment. The ball joint can be used to attach a baluster between rails using a ball joint top and bottom (both ends) of the baluster or attaching the baluster to a top rail only and using a base to attach the baluster to a tread at the bottom. The ball joint may be adjustable in a longitudinal direction only along the length of the rail by pinning the ball joint at 90° to the axis of the rail to form a modular configuration of multiple balusters held by fillet rails of various lengths which can be attached to a rail or (without a plough) accommodated in a rail plough at top and bottom to form an adjustable rail which is variable in length according to the number of modules which are held between the rails. In this configuration the balusters are attached to the fillet rails and the fillet rails are attached to the top and bottom rails—also known as the banister rail and shoe rail. The baluster may also e attached to the top rail using a ball adapter. A socket is used to conform the surface of the rail in multi planar attachment or a hole is drilled to form a socket also allowing a multi planar attachment to the rail. A screw may be used to attach the ball adapter which may be a separate screw or a permanently fixed screw The screw is used to hold the socket in place or in the case of a socket hole it is used to hold the ball in the hole.

The base which is used to attach the bottom of the baluster to a tread may be attached to the tread via base thread or screw. As a part of the baluster attachment to a fillet rail, a clip can also be used as an alternative to drilling pin holes in the fillet rails. The clips are a variation of a socket and the clip socket is independently attached to form a movable socket hole.

OBJECTS OF THE PRESENT INVENTION

It is an object of the present invention to provide a simplified apparatus and method for attaching balusters between a railing and a base surface of a deck, tread, balcony, landing or the like by providing an attachment assembly that permits the installation of a baluster regardless of the angular slope between the railing and a base.

A further object in accord with the preceding object is the provision of an assembly of a ball adapter and a socket that permits the movable adjustment of the angle of a baluster with respect to the slope of a rail to provide for ease of installation of the baluster to the rail and/or a base.

A further object in accord with the preceding objects is to provide for the assembly of a plurality of balusters with a railing insert that will permit the installation of adjustable modules of balusters along spaces in a stair, deck, balcony, or landing.

Further objects and features of the present invention will be readily apparent to those skilled in the art in view of the following specification and drawings.

DETAILED DESCRIPTION OF THE INVENTION

Throughout the following description, specific details are set forth in order to provide a more thorough understanding of the invention; however, the invention may be practiced without these particulars. In other instances, well known elements have not been shown or described to avoid unnecessarily obscuring the invention. Accordingly, the specification and drawings are to be regarded in an illustrative, rather that a restrictive, sense.

FIG. 1 illustrates an assembly 1 of a baluster installation wherein a baluster 11 is shown attached between a top rail 12 and a bottom rail or shoe rail 13 using a ball and socket connector 14 at the top and bottom of the baluster. The connection to the rails includes a ball adapter 15 and a socket 16. The connector 14 assembly is more fully described hereinafter along with its function of providing an adjustable connection of a baluster to a rail, balcony, landing or tread in a stair.

FIG. 2 illustrates, in partial section, the installation of a baluster 11 connection to a top rail 12 having a plough 21 in its lower surface and a fillet rail 22 in the plough and the ball and socket connector 14 attached to the under surface of the plough 22. This sectional view shows the plough and fillet rail at both the top and the bottom of the baluster installation.

The installation of a baluster to a rail system as shown in FIGS. 1 & 2 illustrates the ability of the baluster 11 to be installed in a rail system regardless of the slope of the railing in the ball and socket connector assembly provides for a ball surface 17 to be rotatable within a socket cup 18 of the socket 16 at both ends of the installation.

FIG. 3 illustrates the assembly of a connector 14 wherein a baluster 11 is connected to a sloping top or upper rail 12 and a horizontal base or tread 31. In this figure, the ball adapter 15 includes a ball 17 and an interior cavity 32 open at its bottom end 33 and terminating at it upper end 34 below the ball surface 17. The ball adapter 15 further includes an interior cavity 35 of lesser diameter than the cavity 32 and extending from the upper end 34 of cavity 32 to the center axis of the ball 17 at a shoulder 36 in that cavity 35. The ball 17 then has an extending cavity 37 of pyramidal form (to be described hereinafter) for accommodation of a screw attachment means 38.

The ball 17 engages the socket 16 at an opening 39 having a complementary form for engaging the ball and the interior 40 of the opening 39 is tapered to engage the exterior of the ball 17 and to provide a movable connection between the socket 16 and the ball adapter 15. The socket then has an open end at 41 terminating in a perimeter shoulder 42. The screw attachment means 38 then passes through the internal cavity 32, the further cavity 35 and the pyramidal cavity 37 and can be driven into the underside of a rail 12 to secure the socket 16 to the rail 12 and to engage the ball 17 within the socket. The location of the head of the screw 38 at the intersection of the pyramidal cavity 37 and the cavity 35 permits the ball adapter 15 to be movable side-to-side in two directions of movement with respect to the rail and within the socket cup opening 39.

FIG. 3 also shows another attachment of the baluster 11 to a base or tread 31 wherein a base washer or adapter 24 is secured to the base 31 by a screw 25. A base baluster connector 26 having a hollow interior 27 is adapted to receive the lower end 11 a of a baluster 11. The connector 26 can be axially slidable along the baluster 11 and, as shown in this FIG to be attachable to the exterior of the end 11 a of the baluster and to the base washer 24 by set screws 28. Also as shown in this FIG, the upper end 11 b of the baluster 11 can be attached to the ball adapter by a set screw 29. The installation of a baluster to the form shown in FIG. 3 will be more fully described hereinafter.

FIG. 4 illustrates an alternative form of cooperating assembly of a ball adapter and a socket, and is illustrated in an assembly used with a fillet rail. In this alternative form the socket 16 is attachable to a fillet rail 22 by a screw 45 passing through a hole 46 in the rail and into a threaded portion 47 in the socket 22. The interior of the base of the fillet rail 22 and the exterior of the socket 16 are formed with complementary surfaces to provide a smooth connection between the socket and the fillet rail. The interior 48 of the socket is formed to receive the ball 17 portion of the ball adapter 15. A transverse hole passes 49 through the peripheral edges of the portion of the socket 16 that accommodates the ball 17. The ball 17 includes a transverse hole 50 positioned so that it is aligned with the hole 49 in the socket and the two holes are designed to receive a mounting shaft 51, or pin, for supporting the ball adapter 15 in movable alignment within the socket 16. This movable alignment permits the ball adapter 15 to have limited rotational movement about an axis transverse to the fillet rail 22.

The assemblies shown in FIGS. 3 & 4 are adapted for mounting a baluster to the under surface of a rail or a fillet rail, and as will be described hereinafter, these assemblies could be use to connect a baluster to a base surface of a stair or the like.

The ball 17 for this assembly has an interior transverse hole 68 (not shown) for receiving the pin 67 that is passed through the insert 63 to support the ball 17 for limited rotational movement with respect to the axis of the rail 12.

FIG. 46 illustrates an alternative mounting for the ball adapter 15 within a fillet rail 22 that is adapted to mate with the plough 21 in a rail 12. The fillet rail 22 is constructed with an edge 461 that is large enough to permit a hole to pass through the edge to accommodate a pin 51. The ball 17 of the ball adapter 15 also has a hole (not shown) that passes through its center and is adapted to receive the partial pins 51. The ball adapter 15 is then supported for limited rotational movement about the pin 51 within the fillet rail 22.

FIG. 47 is a three part illustration of the mounting of a baluster between a rail 21 and a base here shown as a tread 31 using a ball adapter 15 and socket 16. In the method shown here and with the apparatus shown, a baluster 11 first has its upper end 11 b inserted into the interior cavity 32of the ball adapter 15 with the ball adapter rotated about its pivotal connection to the rail 12 and/or fillet rail. An internally threaded connector 26 is slideably positioned on the lower end 11 a of the baluster and the baluster is moved to be adjacent to the tread or base 31. A threaded base washer 24 is her shown attached to the base 31 directly below the position of the ball adapter 15 attachment to the rail 21. The upper end 11 b of the baluster 11 is then raised into the inner cavity of the ball adapter a sufficient distance to permit the lower end 11 a of the baluster 11 to be moved to a position directly above the threaded base washer 24 and the lower end 11 a of the baluster is positioned on top of the washer 24. The connector is then threaded onto the washer 24 to lock the alignment of the baluster. A set screw 28 can then be set in the upper ball adapter and the lower connector to fix the baluster against rotational movement. All connections of the baluster to the upper rail and the lower rail have a finished appearance. The mounting of the baluster between the upper rail and the lower base has been accomplished using the apparatus and method of the present invention.

While certain preferred embodiments of the invention have been specifically disclosed, it should be understood that the invention is not limited thereto as many variations will be readily apparent to those skilled in the art and the invention is to be given its broadest possible interpretation within the terms of the following claims.
